Eat your heart out EB fans. This is no b.s. and no I was not drafting a semi, going downhill or gettting pushed by a good tailwind.

Not bad!

 

I can't drive normal so I only see 11-12 :lol (E85 powered)

This average calculation was started with the truck still running ethanol on the trip up (100 miles one way and I went up and back the same day) so it still had 3-4 gallons of ethanol in the tank when I filled it back up with premium fuel for the ride back home.

2012 AWD Sierra Denali 2,300 miles since new (3/27/12) and average mpg is 17.8. One 500 mile and 2-200 mile trips, 55-65 mph 2-lane, no hot-rodding, use cruise all the time, Shell premium 91 octane primarely but a tank or two of Murphy 93 (WM) mixed in, no E85 around here. No mods planned except all AMSOIL 100% synthetic fluids going in before 5,000 miles. That raised my awd CTS4 mpg nearly 1 mpg.

Good to see that! Just called on a 2010 GMC with a 6.2 & asked the salesman to tell me what the avg mpg was... 13.2 with 53,000 miles on it. Hope the guy had a lead foot because I am still going to go check it out.

You know the avg mpg setting can be changed right? I reset mine at each fillup

Did not know that. Have always just left one main one alone. But that was in a 2007 LBZ Dually. Thanks

I usually reset mine at each fill up as well.

Mine probably averages that as well but I only have a 2 mile drive to work and I'm usually running ethanol these days.

 

Don't buy it for the fuel mileage. My post was just to prove that a similarly equipped EB F-150 DOES NOT get a ton better mileage than a 6.2l GM. ESPECIALLY when they are towing a load then the GM 6.2l kills it.

Does that also apply to a 2008 Silverado? If that can be reset I didn't know it and don't know how. My truck was showing 17.6 yesterday when I sold it to my son.

[David_L6]

Not many options other than the Max Trailering Pack.

 

The most important one. looks good

 

 

You got that right!

 

The main reason I wanted a new truck was to get a crew cab. My old truck was an extended cab. Also, the 6.2 with the Max Trailering Pack should make pulling my 7' X 16' enclosed trailer a breeze.

Should be I could in my 08 Tahoe

 

When you hit the mpg screen press and hold the checkmark button

I never reset it in any of my vehicles, the aveage mpg is the only thing of importance to me. My last truck was a 2010 Sierra All Terrain 5.3L E cab and in the 24,000 miles the aveage readout was 17.7 but I also drove almost 1/2 of those miles in winter using AUTO 4x4 mode all the time. The All Terrain pkg rode too rough for my taste.

 

I too never bought it for mileage, needed a CC for business and wanted a top line truck w/o AFM.

If you collect your gas receipt/milage data you can calculate it

 

If you continually reset it you can catch possible issues quick (drastic drops in mpg that would go unnoticed if you didn't reset)

 

To each their own

Just ordered my Auto-Cal from BB. Anticipation is killing me, just like all of you. Any tips from you guys with an Auto-Cal on my next steps when I finally get it? I thought I should receive an e-mail from BB but still waiting. I know they are really busy and a small operation respectively so I guess I will just wait patiently
